Ninja

A general term for any STD. The Ninja creeps up on you when you least expect it to. Having unprotected sex is a good way for the Ninja to get a hold of you.

Guy 1: I haven't been feeling very well lately...
Guy 2: I bet that chick you hooked up with at that party gave you the ninja.

A ninja is a nigga who can't say nigga at the moment. It is especially useful for white niggas who will get beat down or shot for saying nigga around black niggas who don't know them yet, but the word ninja allows the black ninja to say to the white ninja, "Hey, my nigga!"
If anyone edits this post, you are retarded, because this one is actually real.
